It protects branch circuits against overload and short-circuit in industrial control panels and mechanical-engineering installations. Rated breaking capacity is 6 kA per IEC/EN 60898-1 and 30 kA per IEC 60947-2 at 400 V AC. For DC circuits, it's rated 15 kA at 60 V (max 72 V) per IEC 60947-2. Under UL 1077, the supplementary-protector rating is 5 kA. Halogen-free and silicon-free construction, sealable for lockout/tagout.
Width is 54 mm (3 modular width units on a DIN rail). IP20 with conductors connected, so it's for enclosed panels, not wet areas.
